The ceiling speaker that puts a lot of regular box speakers to shame! Combining an audiophile-grade, Kevlar-cone 8-inch woofer with a pivoting aluminium-dome tweeter, then adding switches that let you tune bass and treble to perfection with a 175-watt power handling make the C851 practically bulletproof.

Product Description


Like some of the world's best audiophile speakers, the C851 uses an 8-inch woofer cone made from Kevlar. Kevlar can't stretch, so it produces clean sound with low distortion.

A cast magnesium woofer basket provides a non-resonant frame for the powerful woofer. Proficient's pivoting aluminium tweeter puts out low-distortion highs to complement the woofer's powerful lows. Concealed boost/cut switches let you fine-tune bass and/or treble.

With 28Hz bass response and 175 watts power handling, the C851 lets you crank up even the heaviest rock tunes all day long (if that's what you want to do). And 92dB sensitivity means the C851 needs only about one-third as much power as a typical speaker.

Includes Thin-Bezel Grilles held by Neo Magnets.
